如何在Javascript中显示<embed>内部的字节数组

// 获取<embed>元素
var embedElement = document.getElementById('embedElement');

// 获取字节数组
var url = embedElement.data;
var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.responseType = 'arraybuffer';

xhr.onload = function() {
  if (xhr.status === 200) {
    var byteArray = new Uint8Array(xhr.response);

    // 显示字节数组
    var byteString = '';
    for (var i = 0; i < byteArray.length; i++) {
      byteString += String.fromCharCode(byteArray[i]);
    }

    console.log(byteString);
  }
};

xhr.send();
